Overview
The AD8212YRMZ-RL is a high voltage current monitor amplifier from Analog Devices, designed for precise shunt-based current sensing. It features a single channel with a gain-bandwidth product of 1 MHz and a common-mode rejection ratio of 100 dB. The device operates on a supply voltage ranging from 7 V to 65 V, drawing a typical operating supply current of 720 uA. It offers an input bias current of 200 uA and an input offset voltage of 2 mV. The component supports an extended industrial temperature range from -40°C to +125°C and is housed in an MSOP-8 surface-mount package.
Feature Summary
- Supports high common-mode voltages up to 65 V for flexible placement in power circuits
- Provides accurate differential signal amplification with high common-mode rejection
- Delivers low quiescent current consumption for energy-efficient system designs
Applications
- High voltage current monitoring in industrial motor drives
- Battery management systems requiring precise current measurement
- Power supply overcurrent protection circuits
Procurement Notes
Verify the specific suffix YRMZ-RL against the manufacturer datasheet to confirm package type and reel specifications. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the ordering part number matches the required tape and reel quantity for automated assembly processes.
Selection Notes
Select this component when high common-mode voltage tolerance is required alongside moderate bandwidth. Compare the 100 dB CMRR and 2 mV Vos against application accuracy requirements. Consider the MSOP-8 footprint constraints and the 7 V minimum supply voltage limitation during schematic design.
Part Context
This part belongs to the AD8212 series of current sense amplifiers. It shares the functional architecture with other members like the AD8210 but differs in specific electrical parameters such as gain and common-mode range. The series is optimized for robust performance in noisy power electronics environments.
FAQ
What is the maximum common-mode voltage supported by the AD8212?
The AD8212 supports a common-mode voltage range extending up to 65 V.
Is the AD8212 suitable for bidirectional current sensing?
The AD8212 is primarily designed as a unidirectional current monitor; bidirectional applications typically require devices like the AD8210.
